species ; the articulating head is larger in proportion in the fossil than 

 in the Indian rhinoceros. None of these modifications, however, are 

 excessive ; on the contrary, they are less than those which exist 

 amongst the fossils themselves, which are all three undoubtedly of the 

 same species. 



From the manner in which the lower and exterior part of the great 

 trochanter is broken there is every probability that a descending 

 point protruded from the fractured surface towards the third trochanter, 

 the ascending point of which is very perfect. 



The third trochanter, however, differsfrom that of the existing species 

 as figured in Cuvier's ' Oss. Foss.,' in not possessing the double point ; 

 for it has a single well-defined ascending process, without any sign of 

 the bicuspid termination. The lower edge of this trochanter, instead 

 of ascending with a gradual swell towards the point, as in the existing 

 species, has a counter curvature to that of the upper edge. The chief 

 dissimilarity between Cuvier's plate and the fossil occurs in this part 

 of the bone, the third trochanter assuming a different shape, and 

 offering a variation more distinctive than any other presented in either 

 extremity. This circumstance, together with some of the proportions 

 of the cranium, has led us for the present to distinguish these re- 

 mains by appendifig the word fossil to the name of that species of 

 which they are the prototype. But we dwell on the necessity of more
